"I probably would’ve been like, 'Who does your hair and makeup?'" the pop diva said. "’Cause they had me with some people who didn’t know what they were doing and I knew it wasn’t really good, and I’d just be like, 'Who does your lighting, hair and makeup?'"

Carey also addressed that snap of her wearing lingerie while making brick-oven pizza. The GRAMMY winner, who also donned fabulous furry heels for the occasion, posted the sultry pizza-making pic to her Instagram in April with the caption, "Making #pizza #Italy."

"It was real!" she confirmed, before offering a logical and very Mariah explanation for preparing Italian cuisine in a silk negligee: "That’s what I walk around in! I barely own any clothes! All I have is friggin’ lingerie."

In late April, Carey revealed exclusively to ET that wearing sexy lingerie is just a normal part of being Mariah, joking that, "I wear negligees at home, and then I wear regular clothes when I have to."
As the singer continues her Las Vegas residency at Caesars Palace, entitled "Mariah #1s to Infinity," how, then, has she made herself feel at home in Sin City?

"I just bought a lot of lingerie!" she cheekily responded to PrideSource, laughing.
